By setting a protective plate, the protective plate can be rotated to expand and close by a rotating shaft, and locked by a locking rod, so that the protective plate can be opened during the spraying operation and closed after the operation is completed, effectively avoiding the problem of dust accumulation when the port is exposed after use.

[0007] In the above solution, it should be noted that the motor is electrically connected to the external power supply.

[0020] As a preferred implementation, a spring is sleeved on the outer surface of the guide rod, and two ends of the spring are fixedly connected to the sliding plate and the limiting plate respectively.

[0021] With the above solution, the spring is deformed when the lock rod is separated from the lock hole one and the lock hole two, so the elasticity of the spring can be used to drive the lock rod to quickly return to the lock hole one and the lock hole two, thereby improving the convenience of locking.
